"Actually, sir"? How deliberately belligerent. I note your combative tone and now move on.
I think most people would agree that cars on the road with Bluetooth integration are still rather rare. Nearly everyone, however, owns a radio receiver in their vehicle, home, workplace, cabin, boat, garage, hunting shack, sauna, beach house, etc, etc, etc. It seems to me that the ability to wirelessly send music to those receivers is something many people would like.
Clearly, you are trying to say that manufacturers don't include this feature because they don't think enough people want it. It's a good explanation. I proposed the same idea earlier.
Thank you for your replies.
